Referring more particularly to the illustrative embodiment disclosed in the drawings, the invention comprises a housing or cabinet I providing an enclosure for the unit assembly of automatic service guide and recorder including the novel selecting, projecting and recording mechanism for the complete servicing of various makes and models of automotive apparatus. Within this housing is mounted a motor 2 upon the shaft 3 of which is mounted a roller 4 frictionally contacting a drum 5 for driving a belt (i. As shown in Figure 1, the belt passes over an idler roller or drum 'I freely journalled within an elongated slot in the lower end of a standard or support 9. The belt then passes over an idler roller or drum IU journalled in the support 9, through a projecting apparatus and then over an idler roller or drum II and an idler roller or drum I2, the latter being freely journalled within an elongated slot I3 in the lower end of a standard or support I4. The idler rollers or drums 'I and I 2, due to their free mounting and weight, maintain the belt 6 taut as it passes thereover.

Complete instructions for each make and model of automotive apparatus are printed upon transparent members or micro-films I5 with a sufficient number of the transparent members or micro-films to permit the servicing or lubrication of the various makes and models, being mounted in spaced relation n the belt 6 in such manner that when the drum is rotated and the belt 5 is driven, it will bring into focus in the projecting apparatus the desired transparent member or micro-film carrying the necessary information for servicing that particular make and model.

Movement of the belt is controlled by a floating switch I8, shown in more detail in Figure 9, Iwhich switch contains a spring pressed ball I'I adapted to seat in a selected one of a series of openings I8 in the belt and when positioned in such selected opening disconnects power to the motor and immediately stops rotation of the belt 5. At such time the desired iilm is directly over the lens I9 of the projection apparatus and contact is made whereby the illuminating lamp 2G is energized so that light is projected through the lens El to the mirror 22 (see Figure 2) which reflects the light through the lens I9 and selected film I5 to an enlarging and focusing lens 23, to an angular mirror 24 and upon the transparent screen 25 for visually projecting an enlarged image of the chart selected.

The lamp or illuminating source 20 is placed directly beneath a ventilator 26 and to one side of the belt containing the lrns so as to quickly dissipate the heat from the lamp and prevent its injuring the lm on the belt 6.

When the operator has determined the make and model of automobile or other automotive apparatus to be serviced, he rotates the selector dial 2l which preferably contains the various makes and models and which visually indicates through suitable indicating means thereon when it has been rotated to select the particular make and model of automobile desired. Rotation of the shaft 28 of this dial causes the endless belt to rotate over pulleys 38 and 3l to thereby move the bracket or support 32 carrying the floating switch IG upon its guide or rail 33 until the ball Il carried by this switch drops into the opening i8 opposite or aligned with the designated or desired nlm I 5 and which nlm is brought into registry or directly over the lens iii of the projecting device. At such time, the springpressed plunger 34 forces the ball Il' into the opening and the reduced end 35 of this plunger permits the spring contact 35 to drop to thereby disengage the contacts 3l which supply current to the motor through the wires 38 and 39, and causes the contacts 4l! to be engaged whereby to close the circuit to the illuminating and projection lamp through the wires 33 and 4I.

It will thus be seen that at such time that the motor is stopped from rotating, the belt 6 remains stationary. However, the lamp 29 is energized when the designated chart is brought into focus and light is projected through the film I5 and its associated lens so as to project the enlarged image o-f the chart on the micro-nlm onto the mirror which in turn reflects this enlarged image upon the screen or other transparency 25. Thus the operator has an enlarged illuminated image of the chart and its descriptive matter to guide and permit him to properly service the desired or selected parts of the automotive apparatus, it being understood that the cabinet l may be placed at any convenient place and is suiiiciently small and mobile that it may be moved to any desired location.

In order that the serviced parts may be indicated and a recording thereof made, the invention comprehends the insertion of a printed receipt form 42 into a carrier or receptacle 43 mounted in the front of the cabinet. The printed receipt may be of any desired form but Figure 8 shows an illustrative embodiment having indicated thereon the parts to be serviced and spaced colums to be checked thereon to show that these parts have or have not been serviced. Preferably the receipt is in duplicate.

The carrier or receptacle for the printed receipt is provided with one or more series of longitudinally spaced notches or cut-outs 44 for the reception of an end of a dog or latch 45 secured to an end of a pawl 4i?, the other end 4'I of which is adapted to be received in the toothed or serrated underside of a ratchet wheel 4G. The dog or latch and pawl are pivotally mounted upon the plunger or core 49 of a solenoid 50 suitably mounted within a bracket or support 5I. The ratchet is mounted on the underside of a rotatable drum 52. Thus as the solenoid is deenergized (see Figure 6), the plunger or core 49 is retracted by the spring 53 and in such retraction the end il of the pawl which engages a tooth of the ratchet, rotates the ratchet and drum a predetermined distance. This rotation in turn rotates a carbon ribbon or tape 54 wound about the drum and about the arcuate guides 55 and 5S which provide a channel and guides for the vertical movement of the carrier or receptacle d3. As the plunger or core 49 is forced outwardly upon the solenoid 5B being energized, it raises the dog or latch 45 seating in a slot 44 and in turn elevates the carrier or receptacle 43 a desired amount sufficient to place a new entry on the chart upon a screen to facilitate the servicing operations, a device for performing the servicing operations, and recording means actuated by the operator as he performs such operations for successively making a printed record of the servicing operations as each operation is performed.

5. In a service guide and recording mechanism for the servicing of automotive apparatus, a series of charts containing reduced reproductions and instructions as to the parts of the apparatus requiring servicing, means for selecting a chart of a desired make and model of apparatus, a screen, means for automatically projecting an enlarged image of the selected chart upon the screen, and a recording device including a record having reproductions and instructions similarly arranged to those on the chart and means actuated by the operator as he performs the servicing operations for recording on said record the servicing operations performed.
